hammer [34]

Obasi earns 150% of his regular hourly wage while working overtime.

Let us convert percentage into fraction first:

To convert a percentage into fraction we need to use the following formula:

a%=\frac{a}{100}

Here, he earns 150% of his hourly wage while working overtime:

So,

150%==\frac{150}{100} =\frac{3}{2} =1.5

Obasi earns \frac{3}{2} of his hourly earnings or 1.5 times of his hourly earnings while working overtime.
